Upgraded GPU, cannot render with GPU now (Vegas 11.0 build 511 64-bit)
on Apr 29, 2015 at 4:22:27 pm

A couple weeks ago, I installed a new GPU in my PC, replacing my GeForce GTX 550 Ti with a 750 Ti. Once I tried to render a MainConcept AVC/AAC MP4 video in Vegas, I got the error "An error occurred while creating the media file XXXX. The reason for the error could not be determined." I've looked around for other people having this issue and for the life of me I cannot find any decisive way to fix it.

I've tried rendering with CPU only, which works but is unacceptable as it takes over 2 hours to render a 25-minute video with my quality settings. I tried installing nVidia CUDA (Vegas does say "CUDA Available"), but that had no effect. I also made sure that my new GPU is listed in Vegas' options.

Hopefully someone knows the remedy that I'm unable to locate. Thank you.

Mainconcept AVC does not support newer GPUs. It is hard coded to specific GPUs and Mainconcept has not updated it for years.

For Nvidia this means 6xx (kepler) and newer are unsupported and for AMD 7xxx (Tahiti) and newer.

So what are my options here?

Mainconcept AVC is what it is and it is a fairly slow encoder compared to most others. For AVC targets you can try Sony AVC which should be ~2x faster than 1-pass Mainconcept AVC.

Sony AVC isn't giving me the same amount of customization. I need to render videos in 60 fps, but when I change only the Frame Rate to 60 fps (after switching the file type to .mp4), I get an error that it couldn't save my project, "An invalid argument was specified." Furthermore, Sony AVC is not recognizing my GPU and renders just as slowly as MainConcept.

Maybe I should just go ahead and upgrade to 13.0?

[Anthony James] "Furthermore, Sony AVC is not recognizing my GPU and renders just as slowly as MainConcept."

My 2x comment is in reference to CPU use. I have only used VP12 and VP13 and in these Sony AVC is about 2x faster than MC AVC, pure CPU.

Also to be clear, these two encoders are the only two in Vegas that might use GPU for file encoding, and the encoders have their own GPU option in the render template which is independent from Vegas video engine use of GPU which is controlled via the video prefs option.
